           Summary: Setting track language & kind when the information is
                    in a manifest

Adaptive streaming specs like MPEG-DASH allow language & kind information to be
specified in the manifest instead of only in the initialization segments. We'd
like to be able to reflect this information in AudioTrack, VideoTrack, &
TextTrack objects. The web application needs a mechanism to associate this
information with the appropriate tracks.

Proposed solutions:
1. Remove the readonly modifier from the kind & language attributes on
Audio|Video|TextTrack and allow assignment.
2. Create a Media Source specific method on HTMLMediaElement like the
void sourceSetTrackInfo(in DOMString trackId, in DOMString kind, in DOMString
